Description

Technical Field

[0001] The present application belongs to the technical field of coating machines, and in particular, relates to a fabric coating machine. Background Art

[0002] As we all know, coated fabric is a kind of fabric treated by a special process, which can form a uniform layer of covering rubber on the surface of the fabric, so as to achieve functions such as waterproof and windproof. Therefore, in the process of fabric production, it is often necessary to coat the surface of the fabric with PU glue, A / C glue, PVC or PE glue through a fabric coating machine, and dry it on the surface of the fabric to form a uniform layer of covering rubber on the surface of the fabric, so as to make the fabric waterproof, windproof, etc.

[0003] The existing foreign patent with publication number US20170274579A1 discloses a method for preparing a coated fabric, comprising the following steps: applying a coating solution of a resin in an organic solvent to a non-stretchable and peelable substrate web conveyed by a roller to form a coating layer; laminating the base fabric conveyed by the roller to the coating to form a laminate; guiding the laminate through at least one trough containing water to immerse the laminate in water, thereby curing the coating and replacing the organic solvent contained in the coating with water; and removing water from the coating by drying to leave micropores in the coating.

[0004] Although the above-mentioned coating machine can realize coating the coating material onto the fabric, the coating is often added to the fabric using a separate adding device, resulting in a relatively complicated structure. Improvements are provided for this purpose. Summary of the invention

[0005] The purpose of this application is to provide a fabric coating machine to address the above-mentioned technical problems, which can achieve uniform addition of paint to the fabric and ensure uniform coating of the paint.

[0006] The present application provides a fabric coating machine, including a coating machine body, wherein the coating machine body includes:

[0007] Workbench,

[0008] Conveying rollers are provided, and conveying rollers are placed on both sides of the workbench;

[0009] Scraper, movably mounted on the workbench;

[0010] A conveying mechanism, connected to the scraper, for conveying the coating;

[0011] The scraper is provided with a plurality of evenly arranged discharge holes, the scraper is provided with a feeding cavity connected to the conveying mechanism, the discharge holes are connected to the feeding cavity, and the scraper is provided with a valve group structure corresponding to the discharge holes.

[0012] The textile fabric is coated by passing through the workbench, and the stability of the fabric during movement is improved by the conveying roller. The conveying mechanism provides pressure and coating, and the coating is conveyed to the feeding cavity of the scraper. The feeding cavity is connected with the discharge hole so that the coating can fall evenly on the fabric to be coated, and then the scraper is used to scrape and smooth it. The scraper continuously coats and the coating continuously flows out from the scraper. By integrating the coating feeding structure with the scraper structure, the structure of the coating machine body is more compact, and the space occupied by the coating machine body is reduced. The valve group structure can open or close or adjust the coating discharge state of the discharge hole according to needs.

[0013] Furthermore, the valve group structure includes:

[0014] The valve body corresponds to the discharge hole;

[0015] A valve stem connected to the valve body;

[0016] Adjustment seat, movably mounted on the scraper;

[0019] Wherein, a mounting groove is arranged on the top of the scraper.

[0020] The valve body is connected to the valve stem, which passes through the feeding chamber. The valve stem is installed on the adjusting seat. The electromagnet is energized to control the movement of the valve body and the valve stem. The first spring acts on the valve stem. Under normal circumstances, the electromagnet loses power and the valve body is closed by the first spring. The opening size of the valve body is controlled by the overall adjustment of the adjusting seat, which facilitates the adjustment of the flow rate of the paint.

[0021] Furthermore, the valve group structure also includes:

[0022] A mounting column, mounted on the adjustment seat;

[0023] Wherein, a corresponding electromagnet is installed on the mounting post, and the first spring is sleeved on the mounting post.

[0024] The mounting column is installed and connected with the adjusting seat, the valve stem passes through the mounting column, one end of the electromagnet is installed at the end of the mounting column, and the other end is installed on the valve stem, and the first spring is sleeved on the mounting column to improve the installation stability of the first spring.

[0025] Furthermore, the adjustment seat includes:

[0026] An adjusting worm wheel is movably mounted on the adjusting seat, and the adjusting worm wheel is provided with an internal thread sleeve;

[0027] The worm is movably mounted on the adjusting seat and corresponds to the adjusting worm wheel;

[0028] Wherein, the valve stem is provided with a threaded portion corresponding to the internal threaded sleeve, the worm is provided with a handle, the valve stem is provided with a limiting portion, and the adjustment seat is provided with a limiting seat corresponding to the limiting portion.

[0029] By adjusting the meshing of the worm wheel and the worm, the internal threaded sleeve and the threaded part on the valve stem are connected through a threaded pair, and the handle is connected to the worm. When the handle is rotated, the rotation of the adjusting worm wheel is controlled, and the threaded pair between the internal threaded sleeve and the threaded part is connected to realize the movement and adjustment of the valve stem along the axial direction. The limit part and the limit seat limit the rotation of the valve stem around the axis, thereby improving the accuracy of the movement and adjustment of the valve stem.

[0030] Furthermore, the adjustment seat also includes:

[0031] The adjusting screw is movably installed in the installation slot;

[0032] Guide columns are placed at both ends of the adjustment seat;

[0033] Wherein, the adjusting seat is an adjusting part connected to the adjusting screw.

[0034] Through the threaded connection between the adjusting screw and the adjusting part, the adjusting screw is controlled to rotate to make the adjusting seat rise and fall, so as to facilitate the adjustment of the overall opening size of the valve body. The stability of the adjusting seat during movement is improved by the guide column. The adjusting part is placed in the middle position of the adjusting seat, so that the adjusting seat is more stable during movement.

[0035] Furthermore, it also includes:

[0036] A rotating seat, hinged to the installation shaft of the scraper;

[0039] The scraper is installed on the rotating seat through the mounting shaft. When the end of the fabric passes through the scraper, the scraper needs to be rotated to open. The coating thickness on the fabric is adjusted by rotating the scraper. The clamping seat corresponds to the clamping groove. When the scraper rotates, the clamping seat moves in the clamping groove. When the scraper position is adjusted, the mounting shaft of the scraper is fixed by tightening the clamping seat and the nut to fix the scraper position.

[0040] The beneficial effects of this application are:

[0041] 1. Transport the paint to the feeding cavity of the scraper, connect it with the discharge hole through the feeding cavity, so that the paint can fall evenly on the fabric to be coated, and then scrape it flat through the scraper to achieve continuous coating of the scraper.

[0042] 2. By integrating the coating feeding structure with the scraper structure, the coating machine body is made more compact and the space occupied by the coating machine body is reduced.

[0043] 3. The valve group structure can open or close or adjust the paint discharge state of the discharge hole according to needs. BRIEF DESCRIPTION OF THE DRAWINGS
